Title: Supercritical water oxidation process and apparatus of organics with inorganics
Inventor: MODELL MICHAEL
IPC: B01J3/00
Filed: 1992-06-23
Abstract: 2111847 9300304 PCTABScor01 A method and apparatus is disclosed for oxidation of aqueous mixtures of organic material, including toxic material in the presence of inorganic materials, by reaction of said material with water and oxygen at supercritical conditions. Oxygen and the aqueous mixture are separately pressurized to greater than about 218 atmospheres, combined to form a reaction mixture and then directed through a tubular reactor (12) having a substantially constant internal diameter. The velocity of the reaction mixture is sufficient to prevent settling of a substantial portion of solids initially present in the reaction mixture and of solids which form during passage through the reactor. The mixture is heated to a temperature above about 374· C in the tubular reactor. A substantial portion of the organic material in the reaction mixture is oxidized in the tubular reactor to thereby form an effluent mixture.  Inorganic salts in the effluent mixture, which are insoluble at conditions of supercritical temperature and pressure for water, are dissolved in a liquid water phase during cooldown of the effluent mixture at an outlet end (18) of the reactor. Inorganic solids that are not soluble in the effluent mixture can be separated from a substantial portion of the effluent mixture by filtration prior to subsequent depressurization of the effluent mixture.

Title: Spiral Stent
Inventor: MAEDA MUNEHIRO
IPC: A61F2/06
Filed: 1993-01-14
Abstract: A self-expanding endovascular stent formed of stainless steel wire which is bent into an elongated zigzag pattern. The zigzag pattern has a plurality of substantially straight wire sections of various lengths separating a plurality of bends. The zigzag pattern is helically wound about a central axis to define a tubular shape such that a majority of the bends are disposed in a helix. Adjacent bends in the helix are interconnected with a filament. The stent is capable of being radially compressed such that the straight wire sections and the bends are tightly packed around a central axis. The stent resiliently self-expands to assume a tubular shape when released from the compressed state. Depending on the pattern of the lengths of the straight wire sections in the zigzag pattern, the final tubular shape can be made irregular to match a patient's vascular system. In other words, the diameter of the tube which is defined by the stent can be made to vary along the length of the stent. Stents of the present invention are used to expand a passageway, hold a passageway open, or create a passageway.

Title: Diversity Antenna Structure Having Closely-Positioned Antennas
Inventor: VANNATTA LOUIS J
IPC: H04B7/08
Filed: 1993-12-07
Abstract: A diversity antenna structure (500) and a diversity transceiver incorporating the same are provided.  Each antenna of the diversity antenna structure is formed of a first portion (516, 525) and a second portion (520, 527). Second portions (520, 527) of each antenna are coupled to an electrical ground plane and form thereby ground plane portions of the respective antennas.  Such second antenna (520, 527) are maintained in physical isolation from one another thereby, when receiving high frequency signals, to be maintained in apparent electrical isolation from one another.  Because such ground plane portions are maintained in the apparent electrical isolation from one another, antennas of the diversity antenna structure may be positioned in close proximity to one another without causing coupling between the separate antennas of the diversity antenna structure.

Abstract: CANTILEVERABLE ROLL FOR ROLL PAIR OF PAPER MAKING MACHINE         ABSTRACT OF THE DISCLOSURE               A cantileverable roll for use in a roll press, wherein the cantileverable roll cooperates with a backing roll.  The cantileverable roll has a rotating surface and is either a solid rotatable roll body or a stationary roll body with a rotatable shell around it.  A journal at each end of the cantileverable roll is supported in a respective bearing bracket.  At one end of the roll, preferably the drive end, there is a non-rotating extension piece which extends out axially from the roll body and is fastened to the bearing bracket at that end.  A tension bar or the like connects the extension piece to a stationary structural part and introduces force in the roll body which compensates for the weight of the roll when the other end of the roll is temporarily unsupported and the roll is cantilevered. The backing roll may also be cantilevered.  The various techniques for supporting the one end of the roll by using the coupling element from the extension piece to the frame of the paper making machine are disclosed.  The cantileverable roll and the roll press are particularly useful in a paper making machine.
